An automatic obstacle-crossing cable car comprises a seat board, pulley devices and locking devices. The automatic obstacle-crossing cable car is characterized in that the pulley devices are arranged at two ends of the seat board, and are connected with the seat board through the locking devices; a fixing beam is arranged on the pulley devices, and is used for fixing the pulley devices at the two ends of the seat board. The automatic obstacle-crossing cable car has the advantages that the automatic obstacle-crossing cable car is made of a high-strength light aluminum alloy material, thereby being safe, reliable and portable; the automatic obstacle-crossing cable car can move forwards without disassembly of non-displaced antivibrators on guide lines during maintenance, so that maintenance time of operators is short, physical output is low, and the operators can efficiently complete operations to a high standard.
